------------------------------------

[~eyang] Thanks alot for the help and suggestion, we have already contacted 
infra team, and we are now waiting for some new Aarch64 server to be in place 
for donating, we hope it could be done in next week, so let's wait and see. 
Thanks again for the help.

> As YARN is the resource manager of Hadoop and there are large number of other 
> software that also uses YARN for resource management. The capability of 
> running YARN on platforms with different architecture and managing hardware 
> resources with different architecture could be very important and useful.
> Aarch64(ARM) architecture is currently the dominate architecture in small 
> devices like phone, IOT devices, security cameras, drones etc. With the 
> increasing compuiting capability and the increasing connection speed like 5G 
> network, there could be greate posibility and opportunity for world chaging 
> inovations and new market if we can managing and make use of those devices as 
> well.
> Currently, all YARN CIs are based on x86 architecture and we have been 
> performing tests on Aarch64 and proposing possible solutions for problems we 
> have meet, like:
> https://issues.apache.org/jira/browse/HADOOP-16614
> we have done all YARN tests and it turns out there are only a few problems, 
> and we can provide possible solutions for discussion.
> We want to propose to add an Aarch64 CI for YARN to promote the support for 
> YARN on Aarch64 platforms. We are willing to provide machines to the current 
> CI system and manpower to mananging the CI and fxing problems that occours.
